Interprocedural Optimization: As the name indicates, the optimizations are applied inter procedurally.

Techniques followed are Live Variable Analysis and Global Code Replacement.

Global Optimization: Transformations are applied to large program segments that include functions, procedures, and loops.Techniques followed are Super Local Value Numbering and Loop Unrolling. Regional Optimization: Transformations are applied to Extended Basic Blocks.Techniques followed are Local Value Numbering and Tree Height Balancing. Local Optimization: Transformations are applied to small basic blocks of statements.Usage of registers, and select and move instructions are part of the optimization involved in the target code. Target Code: Optimizing the target code is done by the compiler.Intermediate Code: Optimizing the intermediate code involves changing the address calculations and transforming the procedure calls involved.Source program: Optimizing the source program involves making changes to the algorithm or changing the loop structures.Now that we learned the need for optimization and its two types,now let’s see where to apply these optimization.
